Question

What is the IUPAC name of Brady's reagent, Tollen reagent and Fehlings solution​

Answer 1

Brady's reagent, Tollen's reagent, and Fehling's solution do not have official IUPAC names as they are mixtures. Their components, such as 2,4-dinitrophenylhydrazine for Brady's reagent, silver nitrate for Tollen's reagent, and copper(II) sulfate for Fehling's solution, have IUPAC names.

Step-by-step explanation:

The student's question pertains to the IUPAC names of certain reagents known in chemistry as Brady's reagent, Tollen's reagent, and Fehling's solution. However, these reagents are commonly known by their trivial names, and thus, they do not have official IUPAC names. Instead, their composition can be described using IUPAC nomenclature for the chemicals involved in their preparation.

For example:

• Brady's reagent generally contains 2,4-dinitrophenylhydrazine, which can be described by IUPAC as 2,4-dinitrophenylhydrazine.
• Tollens' reagent is known for its silver mirror test and is prepared with silver nitrate (AgNO3) and aqueous ammonia.
• Fehling's solution is a mixture of copper(II) sulfate (CuSO4), sodium potassium tartrate, and sodium hydroxide (NaOH).

IUPAC names for mixtures are not typically provided, as the IUPAC system focuses on individual compounds.

Answer 2

IUPAC name literally is a chemical organic name given to an organic compound bashing on the IUPAC naming rules.

• Brady's reagent → 2,4-dinitrophenylhydrazine

It is used to confirm presence of carbonyl compounds (compounds with a carbonyl carbon).

• Tollen's reagent → Silver ammonical nitrate solution

It is used to distinguish between terminal and non-terminal alkyns (compounds with carbon to carbon tripple bonds)

• Fehling's solution → Copper (II) sulphate and Silver nitrate solution [ Copper (I) nitrate solution ]

It is used to distinguish between alkanols and aldehydes.

Also it distinguishes between terminal and non terminal alkyns
